Dd you find out what it is?

I'm pretty sure I've had or used one before, but I don't remember where. The top part is for securing a strap or rubber band. As you can see from the wear it's exposed during use, while the bottom is not. The stick has a shape that could be sown into something. My guess is that it is used to close a bag or securing a tarp to a trailer or the hood for a baby pram/stroller. Something to be used outdoors anyway.
